Abstract
A method for measuring stereo image disparity between right and left stereo images for each of two-dimensional blocks having a rectangular shape. In particular, the method includes the steps of deciding a level of each pixel in the right and left stereo images according to a ternary value, sequentially setting a one-dimensional window having a size of N pixels along a horizontal direction in one of the right and left stereo images by overlapping N/2 pixels, determining the disparity for each one-dimensional window by determining a portion in the other of the right and left stereo images corresponding to each one-dimensional window on the basis of the ternary value obtained through the deciding step to generate a histogram of the disparities, and determining the stereo image disparity for each of the two-dimensional blocks on the basis of the histogram of the disparities.
